smoothing is a noise reduction technique that derives its name from the fact that it employs a simple, fast filtering algorithm that sacrifices noise suppression power in order to preserve the high spatial frequency detail (e.g. sharp edges) in an image. It is explicitly designed to remove noise spikes --- i.e. isolated pixels of exceptionally low or high pixel intensity (e.g. salt and pepper noise) and is, therefore, less effective at removing additive noise (e.g.Gaussian noise) from an image. biometrics@hotmail.com

What is filter in digital image processing?
A filter is an effect that can be added to an image that affects the overall appearance, or apearance of a selected area, of an image.
What is digital image processing?
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
What is meant by smoothing in image processing?
With selections, it will try to smooth out jagged edges.
What is image acquisition in digital image processing?
It is the creation of digital image, typically from a physical scene. The term assumed to imply or include processing,compression, storage, printing, and display of such image.
What are the types of image processing?
there are two types of image processing. 1.analog 2.digital.
What is Gaussian low pass filter?
Gaussian low pass filter is a image smoothing filter which is used to smooth up a digital image...........
What is gaussian filter in term of image processing?
the gaussian filter is also known as Gaussian smoothing and is the result of blurring an image by a Gaussian function.
What is filter in digital image processing?

How does the 20x20 filter impact the quality of image processing in digital photography?
A 20x20 filter in digital photography can improve image processing by enhancing details and reducing noise, resulting in sharper and clearer images.
How can the anti-aliasing filter removal be achieved in digital image processing?
In digital image processing, the removal of anti-aliasing filter can be achieved by applying a process called deconvolution. This process involves reversing the blurring effect caused by the anti-aliasing filter to enhance the sharpness and clarity of the image.
What is smoothing in image processing?
Smooth means not sharp, less obvious.

What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).

Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
